`derivable_impls` FN when enum is qualified with `Self`

[profetia]

Summary

derivable_impls FN when enum is qualified with Self in its impl of Default

Lint Name

derivable_impls

Reproducer

I tried this code:

#[derive(Copy, Clone)]
enum Bar {
    A,
    B,
}

impl Default for Bar {
    fn default() -> Self {
        Self::A
    }
}

I expected to see this happen:

The lint is triggered for Bar

Instead, this happened:

Nothing
